swissTLM3D

swissTLM3D is the large-scale topographic landscape model of Switzerland. It includes both natural and artificial landscape features, as well as name data in vector form. With a high degree of accuracy and the incorporation of a third dimension, swissTLM3D is the most extensive and accurate 3D vector dataset of Switzerland.

The large-scale topographic landscape model of Switzerland

Version 1.9

swissTLM3D is available for all of Switzerland and the Principality of Liechtenstein. The current release has the version name swissTLM3D 1.9. A PDF document containing a full overview of the swissTLM3D 1.9 data catalogue, including a list of modifications made in comparison to swissTLM3D 1.8, is available on this site.

New: Street names in swissTLM3D

The 2021 edition of swissTLM3D contains for the first time street names from the official index of streets. In a first step, swisstopo was able to integrate validated street names from 15 cantons. The new information is available as an additional attribute for the road objects.

Cantons with street names in swissTLM3D:

AG, AI, AR, BE, BS, GE, GL, JU, LU, SH, SO, SZ, TG, UR, ZG

Applications

swissTLM3D can be used for a wide range of applications thanks to its simple and clearly defined landscape feature structure:

  • as a reference data set for establishing information systems (e.g. dynamic segmentation based on the road network of swissTLM3D)
  • as a basis for 3D visualisations and analyses (depending on the application, in conjunction with swissALTI3D)
  • as a database for simulations, plans and statistics
  • as a starting point for publications (maps, plans, Internet) and finished products (e.g. multimedia, navigation or geomarketing)

Structure

swissTLM3D describes more than 19 million landscape features, together with their position and shape, the corresponding landscape feature type and many other attributes. swissTLM3D comprises of 8 topics, each of which contains one or more feature classes.

Roads and tracks

Road and path networks

Public transport

Railway lines and other rail systems, shipping routes and public transport stops

Buildings

Buildings, walls, dams, constructions relating to transport, communication, energy, sport and leisure

Areas

Plots with special land usage (transport, nature, habitat, leisure, etc.)

Land cover

Ground coverage independent from land usage

Hydrography

Watercourses and lake contours

Single point objects

Selection of prominent landscape features which aid orientation (crossings, sources, caves)

Names

Various names (mountains, areas, towns, etc.)

File formats

Coordinate systems

swissTLM3D is available in the following Swiss coordinate system:

  • LV95 LN02  

Quality

Geometric accuracy:

  •  For well-defined landscape features such as roads or buildings: 0.2 to 1.5 m in all three dimensions
  • for landscape features which are not clearly defined (e.g. forests): 1 to 3 m in all three dimensions
